Vehicle Seat Device

technical field

The present invention relates to a vehicle seating device which enables the seat to be rotated about a vertical axis relative to the vehicle body.

Background technique

Japanese Patent Application No. 2015-209193 discloses a seat operation control device for rotating a seat having an operating member for adjusting the position of the seat and being rotatable about a vertical axis. In this seat operation control device, the second row of seats provided on the side of the rear side door in a vehicle such as a utility vehicle can operate in two directions inward in the vehicle width direction and outward in the vehicle width direction. Swipe sideways on the S2 range.

Additionally, in the case where the lateral slide position is within ST2 in both directions of the vehicle width direction inner side and the vehicle width direction outer side and when other operating components (seat back, footrest, etc.) are positioned where the seat is rotatable When the seat is within the range, even when the rear side door is closed, the seat can still rotate around the vertical axis without interfering with the rear side door.

However, the seat operation control device having the above configuration secures space for lateral sliding within the range of S2 in both directions of the vehicle width direction inside and the vehicle width direction outside of the seat. For this reason, in the case where the seat operation control device is applied to a vehicle having a small vehicle width dimension, the width dimension of the seat needs to be reduced, and thus there is a possibility that the comfort of the seat may be reduced.

For example, the left and right rear side doors 32 and 34 are sliding doors. The second-row seat 20 is provided on the inner side in the vehicle width direction of the rear side door 34 in the closed state. The rear side door 34 corresponds to a "side door" in the present invention.

As shown in FIG. 2, the second-row seat 20 is equipped with a cushion frame 20A1 and a back frame 20B1, wherein the cushion frame 20A1 is configured as a frame for the seat cushion 20A, and the back frame 20B1 is configured as a frame for the seat back 20B. . A cushion covered by a cover (not shown in FIG. 2 ) is placed on the cushion frame 20A1 and the back frame 20B1 . The lower end portion of the back frame 20B1 is coupled to the rear end portion of the cushion frame 20A1 via the reclining mechanism 36 . The reclining mechanism 36 uses the driving force of the motor 38 to tilt the back frame 20B1 relative to the cushion frame 20A1 about the horizontal axis of the vehicle body.

The cushion frame 20A1 is coupled to the floor F of the vehicle body via a front-rear slide mechanism 40 serving as a front-rear movement mechanism, a side slide mechanism 42 serving as a side-to-side movement mechanism, and a rotation mechanism 44 . As shown in FIG. 3 , the front-rear slide mechanism 40 is equipped with a pair of left and right lower rails 46 , a pair of left and right upper rails 48 , and a front-rear actuator 50 . The left and right lower rails 46 are fixed to the floor F of the vehicle body (see FIG. 1 ) in such a manner that the longitudinal direction of the left and right lower rails 46 coincides with the front-rear direction. The left and right upper rails 48 are supported to be slidable in the front-rear direction with respect to the left and right lower rails 46 . The front-rear actuator 50 uses the driving force of the motor 52 to move (slide) the left and right upper rails 48 in the front-rear direction with respect to the left and right lower rails 46 .

As shown in FIG. 4 , the side slide mechanism 42 is equipped with a pair of front and rear lower rails 54 , a pair of front and rear upper rails 56 , and left and right actuators 58 . The front and rear lower rails 54 are fixed to the left and right upper rails 48 in such a manner that the longitudinal direction of the front and rear lower rails 54 coincides with the left and right directions (vehicle width direction). The front and rear upper rails 56 are supported so as to be slidable in the left and right directions with respect to the front and rear lower rails 54 . The left-right actuator 58 uses the driving force of the motor 60 to move (slide) the front-rear upper rail 56 in the left-right direction with respect to the front-rear lower rail 54 .

As shown in FIGS. 5 and 6 , the rotation mechanism 44 is equipped with a bracket 62 , a gear 64 , a rotation plate 66 , and a motor 68 . The bracket 62 is formed in a substantially rectangular plate shape as shown in plan view, and is fixed to the front and rear upper rails 56 in such a manner that the thickness direction of the bracket 62 coincides with the up-down direction. The gear 64 is formed in a disk shape and is provided below the bracket 62 such that the axial direction of the gear 64 coincides with the up-down direction, and is supported rotatably about the vertical axis of the vehicle body relative to the bracket 62 . The rotary plate 66 is formed in a disc shape and is provided above the bracket 62 such that the axial direction of the rotary plate 66 coincides with the up-down direction, and is supported rotatably about the vertical axis of the vehicle body relative to the bracket 62 . A center portion of the rotating plate 66 and a center portion of the gear 64 engage with each other so that the rotating plate 66 and the gear 64 rotate integrally. External teeth 64A are formed on the outer periphery of the gear 64 . The pinion 70 is fixed to the output shaft of the motor 68 and the external teeth 64A mesh.

The motor 68 is provided below the bracket 62 and fixed to a part of the outer peripheral portion of the bracket 62 . When the pinion gear 70 is rotated by the driving force of the motor 68 , the gear 64 that meshes the pinion gear 70 with the external teeth 64A of the gear 64 rotates integrally with the rotary plate 66 . A plate frame 20A11 configuring a bottom portion of the cushion frame 20A1 is fixed to an upper surface of the rotary plate 66 . For this reason, when the motor 68 rotates, the cushion frame 20A1 rotates integrally with the rotating plate 66 and the gear 64 about the vertical axis of the vehicle body (hereinafter simply referred to as “about the vertical axis”).

The center console 26 shown in FIG. 1 is coupled to the floor F of the vehicle body via a center slide mechanism 72 serving as an obstacle moving mechanism. The configuration of the central slide mechanism 72 is basically the same as that of the front-rear slide mechanism 40, and the central slide mechanism 72 uses the driving force of a motor 74 (see FIG. 8, not shown in drawings other than FIG. The console 26 moves (slides) in the front-rear direction relative to the vehicle body. Specifically, the central sliding mechanism 72 can make the central console 26 in the front-row position set between the left and right front seats 14 and 16 and between the left and right second-row seats 18 and 20 in the front-rear direction. Swipe between second row positions.

Here, in the present embodiment, in a state where the center console 26 is disposed at the front row position shown in FIG. . The side slide mechanism 42 moves the second-row seat 20 relative to the vehicle body in the vehicle width direction between a normal area where the second-row seat 20 is conventionally arranged and an inner area set inside the normal area in the vehicle width direction. .

It should be noted that an imaginary circle C1 shown in FIG. 7 represents a rotation region when the second-row seat 20 disposed on the frontmost position side of the sliding range in the front-rear direction in the normal region has been rotated about the vertical axis, and FIG. A point P1 shown in 7 represents the center of the imaginary circle C1. In addition, an imaginary circle C2 shown in FIG. 7 represents a rotation area when the second-row seat 20 provided on the rearmost position side of the sliding range in the front-rear direction in the normal area has been rotated about the vertical axis, and FIG. 7 The point P2 shown in represents the center of the imaginary circle C2. In addition, an imaginary circle C3 shown in FIG. 7 represents a rotation region when the second-row seat 20 provided on the side of the frontmost position of the sliding range in the front-rear direction in the inner region has been rotated about the vertical axis, and FIG. 7 P3 shown in represents the center of the imaginary circle C3. In addition, an imaginary circle C4 shown in FIG. 7 represents a rotation region when the second-row seat 20 provided on the rearmost position side of the sliding range in the front-rear direction in the inner region has been rotated about the vertical axis, and FIG. 7 The point P4 shown in represents the center of the imaginary circle C4.

As indicated by the imaginary circles C1 and C2, in the state where the second-row seat 20 is arranged in the normal area, the rotation of the second-row seat 20 around the vertical axis is due to the contact between the rear side door 34 and the second-row seat in the closed state. Interference between chairs 20 is limited. On the other hand, as indicated by the imaginary circles C3 and C4, in the state where the second-row seat 20 is disposed in the interior area, the second-row seat 20 can be rotated about the vertical axis without contact with the rear side door in the closed state. 34 interference occurred. Furthermore, in a state where the center console 26 is arranged at the front row position as shown in FIG. 7 , the center console 26 is arranged outside the swivel area of the second-row seat 20 .

Furthermore, in the present embodiment, as shown in FIG. 8 , the motors 38 , 52 , 60 , 68 and 74 are equipped with motor bodies 38A, 52A, 60A, 68A and 74A and encoders 38B, 52B, 60B, 68B and 74B. The motor bodies 38A, 52A, 60A, 68A and 74A and the encoders 38B, 52B, 60B, 68B and 74B are electrically connected to an ECU 76 serving as a control device. For example, the ECU 76 is provided in the seat cushion 20A of the second-row seat 20 . The ECU 76 is equipped with control parts, ROM, RAM, input/output interfaces, drive circuits, and the like connected to each other via a bus. Programs for controlling the operations of the motors 38 , 52 , 60 , 68 and 74 are stored in the ROM. Further, a door sensor 77 that detects the open/closed state of the rear side door 34 is electrically connected to the ECU 76 .

The ECU 76 determines the reclining position of the seat back 20B of the second-row seat 20, the front-rear direction position of the second-row seat 20, the second-row seat 20, the rotational position of the second-row seat 20 about the vertical axis, and the front-rear position of the center console 26 are detected. The angled front left mode switch 78 , the angled front right mode switch 80 , the entry/exit mode switch 82 , the face-to-face seating mode switch 84 , and the angled face-to-face seating mode switch 86 are electrically connected to the ECU 76 . When any one of these switches 78, 80, 82, 84, and 86 is operated, the control section of the ECU 76 executes the program stored in the ROM while utilizing the temporary storage function of the RAM. For this reason, the ECU 76 rotates the second-row seat 20 to a position corresponding to each switch mode.

Here, when the ECU 76 causes the rotation mechanism 44 to rotate the second-row seat 20, the ECU 76 causes the side-sliding mechanism 42 to move the second-row seat 20 from the regular area to the interior area before the rotation. In addition, the ECU 76 causes the center slide mechanism 72 to move the center console 26 out of the swivel area of the second row seats 20 before causing the side slide mechanism 42 to move the second row seats 20 from the regular area to the interior area. Further, the ECU 76 causes the front-rear slide mechanism 40 to move the second-row seat 20 to the front-rear direction reference position and the reclining mechanism to The seat back 20B moves to the reclining reference position.

The control of the ECU 76 in the case where the oblique front left mode switch 78 has been operated will be described below using the flowchart shown in FIG. 9 . It should be noted that FIG. 9 shows the control flow of the ECU 76 in the case where the oblique front left mode switch 78 is set at the second row position (the position shown in FIG. 1 ) on the center console 26 and the second row The seat back 20B of the seat 20 has been operated in a reclined state as shown in FIG. 10A . First, in step S1 , the ECU 76 judges whether or not an open signal has been output from the oblique front left mode switch 78 . In the case of NO, the ECU 76 continues the process in step S1, and in the case of YES, moves to step S2.

In step S2, the ECU 76 activates the motor 74 of the center slide mechanism 72 to slide the center console 26 from the second row position to the front row position (see FIG. 10A). When the process in step S2 is completed, the ECU 76 moves to step S3.

In step S3, the ECU 76 activates the motor 52 of the front-rear slide mechanism 40 to slide the second-row seat 20 to a preset first front-rear direction reference position (the position indicated by the solid line in FIG. 10B ). When the process in step S3 is completed, the ECU 76 moves to step S4. It should be noted that the illustration of the front and rear sliding mechanism 40, the central sliding mechanism 72, etc. is omitted in FIGS. 10B to 11E for easier viewing of the drawings.

In step S4, the ECU 76 activates the motor 38 of the reclining mechanism 36 to recline the seat back 20B to a preset reclining reference position (the position indicated by the solid line in FIG. 10C). When the process in step S4 is completed, the ECU 76 moves to step S5.

In step S5, the ECU 76 activates the motor 60 of the side slide mechanism 42 to slide the second-row seat 20 from the regular area to the inner area (see FIG. 10D ). When the process in step S5 is completed, the ECU 76 moves to step S6.

In step S6, the ECU 76 activates the motor 68 of the rotation mechanism 44 to rotate the second-row seat 20 to the oblique front left position (the position indicated by the solid line in FIG. 10E). When the process in step S6 is completed, the control routine ends.

It should be noted that in the case where the switch that has been operated is the oblique front right mode switch 80 instead of the oblique front left mode switch 78, the ECU 76 performs the same operation in steps S1 to S5 as in the case where the oblique front left mode switch 78 has been operated. The process is the same. Thereafter, in step S6, the ECU 76 rotates the second-row seat 20 to the oblique front right position (the position indicated by the solid line in FIG. 10F). It should be noted that in this case, in the present embodiment, the amount of inward movement of the second-row seat 20 in the vehicle width direction in step S5 is set to be greater than that in the case where the oblique front left switch 78 has been operated. The amount of movement is small.

Further, in the case where the switch that has been operated is the entry/exit mode switch 82, the ECU 76 performs the same process in steps S1 to S5 as in the case where the oblique front left mode switch 78 has been operated. Thereafter, in step S6, the ECU 76 rotates the second-row seat 20 to the entry/exit position (the position indicated by the solid line in FIG. 10G). It should be noted that in this case, in the present embodiment, the inward movement amount of the second-row seat 20 in the vehicle width direction is set in step S5 to be greater than that in the case where the oblique front right switch 80 has been operated. The amount of movement is small. This also applies to the case where the face-to-face sitting mode switch 84 and the inclined face-to-face sitting mode switch 86 have been operated. Furthermore, the ECU 76 enables the operation of the entry/exit mode switch 82 only in a state where the door sensor 77 detects that the rear side door 34 is open.

Further, in a case where the switch that has been operated is the face-to-face sitting mode switch 84, the ECU 76 executes the processes of steps S1 and S2, and thereafter, in step S3, the ECU 76 moves the second-row seat 20 to the second front-rear direction reference position (the position indicated by the solid line in FIG. 11A ), which is different from the case where the oblique left front mode switch 78 has been operated. Next, in steps S4 and S5, the ECU 76 performs the same process as that in the case where the oblique front left mode switch 78 has been operated (see FIGS. 11B and 11C ). Thereafter, in step S6, the ECU 76 rotates the second-row seat 20 to the face-to-face seating position (the position indicated by the solid line in FIG. 11D).

Furthermore, in the case where the switch that has been operated is the inclined face-to-face sitting mode switch 86, in Step S1 to Step S5, the ECU 76 performs the same process as that in the case where the face-to-face sitting mode switch 84 has been operated. Thereafter, in step S6, the ECU 76 rotates the second-row seat 20 to the inclined face-to-face seating position (the position indicated by the solid line in FIG. 11E).

Next, actions and effects of the present embodiment will be described.

In the vehicle seat device 10 having the above configuration, when the ECU 76 causes the rotation mechanism 44 to rotate the second-row seat 20 disposed on the vehicle width direction inner side of the rear side door 34 about the vertical axis relative to the vehicle body, the ECU 76 The side slide mechanism 42 is caused to move the second row of seats 20 from the regular area to the interior area prior to rotation.

In the state where the second-row seat 20 is arranged in the normal area, the rotation of the second-row seat 20 around the vertical axis is due to the interference between the rear side door 34 in the closed state and the second-row seat 20 (see FIG. The imaginary circles C1 and C2 in 7) are restricted. On the other hand, in the state where the second-row seat 20 is arranged in the interior area, the second-row seat 20 can rotate about the vertical axis without interfering with the rear side door 34 in the closed state (see FIG. 7 ). imaginary circles C3 and C4). For this reason, interference between the second row of seats 20 and the rear side door 34 is prevented when the second row of seats 20 is moved to the interior area and then rotated about the vertical axis as described above. In addition, it is sufficient to secure a space for movement in the vehicle width direction (sideways sliding) only on the inside of the vehicle width direction of the normal area where the second row of seats 20 is conventionally arranged, so it is easy to secure the space for the second row of seats 20 . Width dimension (see arrow W in Figure 1).

Furthermore, in the present embodiment, the vehicle seat device 10 is equipped with the center console 26 provided on the vehicle width direction inner side of the second-row seat 20 positioned in the normal area, and the center slide mechanism 72 . , the center slide mechanism 72 moves the center console 26 to a forward position positioned outside the swivel area of the second row of seats 20 . Additionally, the ECU 76 causes the center slide mechanism 72 to move the center console 26 out of the swivel area of the second row seats 20 before causing the side slide mechanism 42 to move the second row seats 20 from the regular area to the interior area. For this reason, even in the configuration equipped with the center console 26 , the second-row seat 20 can be rotated about the vertical axis in the closed state of the rear side door 34 .

Furthermore, in the present embodiment, the vehicle seat device 10 is equipped with a front-rear sliding mechanism 40 that moves the second-row seats 20 in the front-rear direction relative to the vehicle body, and a reclining mechanism 36 , and the front-rear sliding mechanism 40 40 has a first front-rear direction reference position and a second front-rear direction reference position set within a moving range in the front-rear direction, and the reclining mechanism 36 makes the seat back 20B of the second row seat 20 relative to the seat cushion 20A reclined and has a reclining reference position set within the reclining range of the seat back 20B. Additionally, the ECU 76 causes the front-rear slide mechanism 40 to move the second-row seat 20 to the front-rear direction reference position and the reclining mechanism 42 before causing the side slide mechanism 42 to move the second-row seat 20 from the regular area to the inner area. The seat back 20B is moved to the reclining reference position. That is, the second-row seat 20 moves in the vehicle width direction after the front-rear direction position of the second-row seat 20 and the reclining position of the seat back 20B have been adjusted to certain positions. For this reason, it is easier to prevent the second row seat 20 from moving in the vehicle width direction in a state where the front-rear direction position of the second row seat 20 and the reclining position of the seat back 20B are not specified. Interference between the seat row 20 and surrounding objects.

It should be noted that although in the present embodiment, the vehicle seat device 10 has a configuration equipped with the center console 26 and the center slide mechanism 72, the vehicle seat device 10 is not limited thereto. For example, the vehicle seat device 10 may also have a structure in which the center console 26 and the center slide mechanism 72 are omitted, and the space between the front seats 14 and 16 and the left and right second-row seats 18 and 20 is a walking space. type.

Furthermore, in the present embodiment, the vehicle seat apparatus 10 has a configuration in which the center console 26 is an obstacle, but the vehicle seat apparatus 10 is not limited thereto and may also have, for example, a configuration in which the center seat is an obstacle.
